A a hot strip mill reel may be formed; or a @t The present invention relates broadly to suitable supporting frame preferably coml0 reels and moreparticularly to reels adapted prising side standards 2 which may be oi :tor use with rolling mills producing strips, substantially similar construction. rll`hese the word strips being used in its generic standards are adapted to receivev therebesense as covering shapes havinga substantween and operatively support a series of @e tially rectangular section, or section of such guiding devices adapted to co-operate with nature that the material is adapted to .be the strip as it is fed to the reel. rlhese guid wound into a helix or series oi supeiiming devices may conveniently comprise a posed coils. series of rolls 3 and intermediate deectors lt is customary at the present time for il.' rlhese rolls and deflectors form a subte strip mills to deliver strips at a speed of stantially enclosed circular ceiling space.

The arms 8 and ln the drawings, 9 may conveniently be formed as castings mi@ Figure 1 is a side elevation of a reel emhaving their inner ends connected to forni bodying the present invention; the deflectors 4 and having theirouter ends Figure 2 -is an end elevation or the conconnected bg hubsv 10 of a length substan struction shown in Figure l; tially exten ing from standard to4 standard to thereb devices,

vposition in any desired manner as by bolts 11 any number of which may be rovided.

At the outer end of the guide the guide roll.3'1 is carried between the standards on pivot l2, This pivot also supports arms 12 shown in detail in Figure 3, which arms carry the upper pinch roll 5. The firs't deiiector 4 may be carried by arms 13, afs illustrated in detail in Figure 4. While all of the different arms provided mi ht be of similar construction, the modifie construction herein disclosed has been found desirable from a constructional and assembly standpoint, the arrangement permitting a compact organization. Each. pair of arms 8, 9, 12 and 13, has extending outwardly therefrom a crank arm 14 which crank arms co-operate with tension springs 15 for continuously exerting a pull on the crank arms effective `for urging the guiding devices, with the exception of the roll 3, inwardly These springs at the same time permit all` of the guiding devices to move outwardly as the diameter of the coil increases.

The inward movement of the guidingdevices may be checked in any desired manner. For this purpose there may' be provided links 16 for certainof the guiding devices, which links are secured at their outer ends -to the bolts which hold the arms in position in the supporting frame and at their inner ends are provided with hooks 17 adapted to engage the axes of the rolls 3. The arms 13 may conveniently be controlled by a stop 18 formed on one of the side standards and adapted to co-operate with an abutment 19 on the' crank arm 14. Each of the springs 15 may have its tension adjustably controlled in any desired manner, as will be ap-- parent. i

In order to decrease the friction exerted on the strip being coiled, the rolls 3, together with the rolls 3a and 3b which are directly carried between the side standards, are all adapted to be positively driven. This action may be accomplished by extending the axes of all of'these rolls beyond one of the side standards2 and connecting thereto one end of a drive shaft 20 having a universal joint 21 at each end thereof. These universal joints may be of any well known construction and are preferably so secured to the shafts 20 as to permit the distance between the universal joints to increase or decrease without destroying the driving relationship. Thisv arrangement will take care of the outward movement of the guiding devices and yenable 'the' rolls to be continuously driven. At their'outer ends all of the shafts 20 may be supported in a supplemental standard 22 having a series of bearings 23 for the shafts. Each of the shafts has secured thereto a gear 24 all of which natanti gearsv are inturn-driven b large ear ,25 mounted on a shaft 26 an adapte to be driven by a pulley 27. ll have also .illusextended and connected to a shaft 2O whereby thepinch rolls trated the shaft for the pulley 6 as being 5 may be driven simultaneously with all of the guiding rolls.

The present invention enables a hot strip to be coiled into compact shape as it is delivered from the last roll stand. As the guiding devices are all movable about axes which are parallel, the strip is caused to form a series of superimposed convolutions so that the entire body of rolled material is maintained in position between the stand! ards 2. In this manner, the possibility of injury to the workmen is negatived and the space heretofore required for the looping of the hot metal may be utilized for other purposes. These constitute advantageous features of the invention.

This invention also overcomes the objections inherent in the use of a hot bed, such as heretofore sometimes used for the strips. The length of the hot bed limits the weight of the billet being rolled, as'the length of the strip produced therefrom must not exceed the length of the hot bed. The present. reel takes care of varying lengths of material vin much less space thanv has heretofore been possible.
